Read the passage given below and answer the following question.
According to Hardy-Weinberg principle, the allele frequencies in a population are stable and remain constant through generations. The gene pool (total genes and their alleles in a population) remains a constant. This is called genetic equilibrium .Sum total of all the allelic frequencies is 1. (A) Write the equation representing Hardy-Weinberg equilibrium.

List the factors that affect the genetic equilibrium.
Answer & explanation
Correct answer: option 1
The factors which affect the Hardy Weinberg equilibrium are: gene migration or gene flow , genetic drift , mutation, genetic recombination and natural selection. When migration of a section of population to another place occurs , gene frequencies change in the original as well as in the new population .
